Adrian Peterson, 26-year-old Minnesota Vikings’ running back, went down last Saturday with what is sometimes called an “Unhappy Triad”. The “unhappy” part is obvious. The “triad” is, because the injury represents a triple threat.

The metacarpals (MCs) are the long bones in the hand that extend from the small carpal bones (that comprise part of the wrist) to the base of the fingers. The MCs are most often fractured due to impact with a closed fist.

In re-reviewing the updated NFL injury reports I stand corrected on Tuesday’s post regarding the prevalence of ACL tears suffered by players this season. I’d counted ten, and the number appears to be at least 15, or possibly 16.

There have been so many season-ending injuries in the NFL this season, and complete ACL tears seem to lead this category. By my count, there are already 10 players who are looking on from the sidelines after having ACL surgery.
